When beats are produced by two progressive waves of the same amplitude and of nearly the same frequency, the ratio of maximum loudness to one of the waves will be n, Where n is:
Text Solution
Verified by ExpertsThe correct answer is:
C
We know that intensity 
,
where 
is amplitude of the wave.
The maximum amplitude is the sum of two amplitudes
i.e., 
Hence,
maximum intensity 
Therefore the required ratio
i.e., ratio of maximum intensity (loudness) and intensity (loudness) of one wave is given by 
,
